WHY MATRIX REPAIR MATTERS

Even the best models collapse if the math underneath is unstable. Ill-conditioned matrices (those with very large condition numbers) can turn your optimizers, regressions, covariance, or risk models into random number generators — often at the worst possible time.

WHAT WE DO

We apply proprietary theorems & algorithms, based on new discoveries that apply to ALL square matrices (real or complex), to stabilize your matrices quickly and transparently:

  • Minimal, auditable edits — the structure of your matrix is preserved, only the unstable parts are corrected.

  • CONDITION NUMBER REDUCTION — typically 1–2 orders of magnitude, often around 90% or more.

  • FAST TURNAROUND — you send us your matrix, we return a repaired version plus a full report in about one day.

WHAT YOU RECEIVE

  • Your original & repaired matrix (same format you sent).

  • A before/after condition number comparison (κ values).

  • Heatmaps and charts showing stability gains.

  • A simple audit trail of all changes.

EVALUATION FIRST

Every case is different. That’s why we offer an evaluation run at no cost. You’ll see the repaired matrix, the κ drop, and the edits — and test the improvements in your own models.

If the stability and precision gains meet your needs, we can discuss ongoing support.

About Fraud Detection Algorithms

FDA was created by Raul Garcia who has a Master in Mathematics from the University of California San Diego (UCSD), and is a professional software developer.

Most fraud software is only for the big guys online ordering systems, no one cares about the smaller Romance Scams victims - possibly you!.

But there are hundreds of thousands of victims WoldWide and their losses are from $100 to $200,000 by using sophisticated protocols to scam any type of victim. It is a criminal enterprise.

Crypto payments or offers (get rich), direct bank payments (both not recoverable) and gift cards are common devices to separate you from YOUR Money permanently.

Many do not report the loss or talk about it due to shame, but this is trick they use to hide this...

We developed an excel program that has 15 YES/NO QUESTIONS and scores them using a weighted scale algorithm. The final score indicates the danger of a romance scam.

It also has TABs with information and links to the BBB and FTC and more for YOUR education, such as Free videos on amazon of some UK scams.

On the BBB site below you can read from thousands on stories by REAL VICTIMS and learn from them the many ways anyone can be scammed.

Do You know the most common way that corporate FRAUD is detected?

It is NOT by auditing etc. - it is from Whistleblowers! This is untenable - FDA uses sophisticated algorithms like the powerful legally accepted Benfords Law.

We can do the Benfords analysis law within a week in Excel format for ease of use. BL points right to the suspect amounts you NEED to check to protect your money and firm.

-- AUDITORS --

Soon FDA will release a set of Excel workbooks that can do the Benford's Law analysis for 1,2 or 3 1st digits for a VERY PRECISE flagging of anomalies and possible fraud.

1-2 digits is ideal for small/medium size companies, 3 digits for large companies with 10's of thousands of transactions.

These tools are IDEAL for Payables data - where it is so easy to hide fraud due to a very large number of transactions.
